Diagnostic procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture of the PC function. • Record the freeze frame data/snap shot data.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Switch the ignition off. • Disconnect the TCM connector. • Inspect for poor connection at TCM terminals 1D and 1C (such as damaged/pulled-out pins, corrosion). • Are terminals normal?	Yes	Go to the next step.
3		No	Repair or replace the connector and/or terminal, then go to Step 10.
4	INSPECT CONTINUITY OF VSS CIRCUIT • Inspect for continuity between the coupler component terminals 1D and 1C (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
4		No	Go to Step 7.
5	INSPECT VSS SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between the TCM terminals (wiring harness-side) and body ground. ― Terminal 1D and body ground ― Terminal 1C and body ground • Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • VSS terminal B—TCM terminal 1D • VSS terminal A—TCM terminal 1C If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to ground. Go to Step 10.
5		No	Go to the next step.
6	INSPECT VSS CIRCUIT FOR SHORT TO POWER SUPPLY • Switch the ignition ON (engine off). • Measure the voltage at TCM (wiring harness-side) terminals 1D and 1C. • Is there 0 V at the TCM wiring harness-side connector terminals?	Yes	Go to the next step.
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • VSS terminal B—TCM terminal 1D • VSS terminal A—TCM terminal 1C If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to power supply. Go to Step 10.
7	INSPECT TERMINAL VSS FOR POOR CONNECTION • Switch the ignition off. • Disconnect the VSS connector. • Inspect for poor connection at VSS terminals A and B (such as damaged/pulled-out pins, corrosion). • Are terminals normal?	Yes	Go to the next step.
7		No	Repair or replace the connector and/or terminal, then go to Step 10.
8	INSPECT VSS • Inspect the VSS. (See VEHICLE SPEED SENSOR (VSS) INSPECTION [SJ6A-EL].) • Is the VSS normal?	Yes	Go to the next step.
8		No	Replace the VSS, then go to Step 10. (See VEHICLE SPEED SENSOR (VSS) REMOVAL/INSTALLATION [SJ6A-EL].)
9	INSPECT VSS CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between VSS terminals (wiring harness-side) and TCM terminals (wiring harness-side). ― Terminal B and terminal 1D ― Terminal A and terminal 1C • Is there continuity?	Yes	Go to the next step.
9		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • VSS terminal B—TCM terminal 1D • VSS terminal A—TCM terminal 1C If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to the next step.
10	VERIFY SAME DTC IS NOT PRESENT • Always reconnect all disconnected connectors. • Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Warm-up the engine and transmission. 3. Drive the vehicle in D position and make sure that the gears shift smoothly from 1GR to 6GR. • Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
10		No	Go to the next step.
11	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) • Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (SJ6A-EL)].)
11		No	DTC troubleshooting completed.
